ELECTRICAL CONTROL To all whom it may concern:

Be it known that I, Corn ,S'ri'cnrn, a citi zen of the United States, and a resident oi Indianapolis, county of Marion, and State '01" Indiana, have invented a certain new and useful Electrical Control for Paper-Making Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

' The object of this invention is to control the heat supply to the cylinders of a paper the tension of the.sheet of paper or other sheet going through the machine, as said tension is changed by changes in the moisture of the sheet. When the sheet becomes "relatively dry it will shorten, and through means, such as herein indicated, will reduce or shut ofi the heat supply to the cylinders until the heat imparted to the sheet is reduced so that the sheet will not be too dry. When the heat is reduced and the sheet becomes too moist it will lengthen relatively and through the means, as herein indicated, will control the heat supply so as to increase the heat and dry the paper more. In this way, the sheet of paper orother material, as the tension changes through changes in moisture, will automatically regulate, the heat for drying the sheet.

This invention is not limited to any particular means for carrying out this object."

That'shown herein consists of an electric switch with mechanism acted upon by the sheet of paper orthe like, as it passes ovens the cylinders and through the machlne, so

that when the sheet becomes relatively dry, it will shorten and close the circuit .and through an intermediate electrical apparatus close the valve in the heating apparatus so as to reduceor cutoff the supply ofheat to the cylinders. 'Vl"hen the heat is not sufficient to dry the sheet, its moist condition will somewhat lengthen the sheet so that the electrical cont-act switch will open thecir cult and through intermediate means cause.

the valve to open and admit more heat.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims. I

per 12 passes through the machine. The sheet of paper is dried by steam being intrcduced into said cylinders through individual pipes 13 leading from the header 14. The live steam comes in under high pressure through a'high pressure pipe 15. A reduction valve mechanism 16 is provided for reducing the pressure of the steam as it enters the header. The reducing valve mechanism 1G is controlled by water under pressure passing thereto through a Icy-pass pipe 17 from a, high pressure water pipe 18. lhc details of the construction otlfiig reclucing valve mechanism 16 are "not shown as it is of common type, but itis so arranged that ,when the Amer under pressure passes fthrongh 'pipelY-the valve will tend to close anfi when the water under pressure is shut oil passing through pipe 17, the valve egll be open. The passage of water under pressure from the high pressure pipe 18' to.

the by-pess 17 is controlled by an auxiliary valve 19which is opened by a solenoid 20 in a magnet 21 when it is energized by the current passing through lines 22 and 23.

Current comes to this machineover aunain line 24 and branch 25 teen electrical switch controlled by a sheet of paper and hereafter-- explained and through said switch paws to line 22 and goes out over line 23 and through a line 26. There is a shunt line?! having an indicating lamp 28 to indicate whether the valve controlling circuit is open or closed. The means whereby the sheet of paper controls said valve closing circuit is illustrated in Figs. 2, 3 and 4. There is-a bearing sleeve 30 carried by a bracket 42 secured to the upright frame member ll) by screws 31 and the same construction is o the opposite side of the machine and in the arm 33 rigidly connected therewith at each end ofa cylinderll and the outer ends of said arms carry a loose roller 85 which extends transversely of the machine below and to the front of said cylinder and bears against the inner surface of the sheet 12 as it' travels over said cylinder.

On one end of said rod 32 acontact arm 36 is rigidly secured between its ends. The short end of said contact arm 36'opcrates i between two stop screws 37 in ears 38 connected with the frame so as to,limit the oscillation of the arm 36. The long end of said arm 36 carries an adjustable contact 39 adapted to cooperate with a contact 40 adjustably mounted on a rigid arm 41 secured to said bracket 42.

The arms 33 extend upwardly and rear wardly from the rod 32, as shown in Figs.

3 and 4, so that their weight and the weight of the roller will tend to move the contact arm 36 by gravity down to the open position shown in Fig. 3, and thus open the circuit whenever the sheet of paper has become slack enough by being too moist and allows paper better.

such action. When that happens and the circuit is open, the magnet 21 is not energized and, therefore, 'the solenoid 20 drops and causes the closing of the valve 19 which shuts off the water under pressure passing through pipe 17 for holding the' reducing valve at 16 in closing or reducing position and that opens the reducing valve and admits more steam or head to the cylinders so as to impart more heat to them and dry the If, on the other hand,'the sheet of paper has become relatively dry, it shortens or takes up its slack, as indicated in. Fig. 4, and moves the roller 85, arms 33, rod 32 and contact arm 36 so as to close the circuit and when the circuit is closed the magnet 21 will be energized, the solenoid elevated, the auxiliary valve 19 opened and water under pressure will pass through pipe 17 and move the reducing valve to a position for decreasing the supply of heat to the cylinders.

The invention is not limited .to the particular switch means shown or to the valve arrangement, as it consists in utilizing the change in the slackness or tautness .oi" the sheet of paper or other sheet for, tl'irough suitable intermediate mechanism, controlling the reducing valve or other valve which controls the heat supply.
